There are three types of underwater welding: dry method, wet method and partial dry method.
Dry welding
This is a method in which a large air chamber is used to cover the weldment, and the welder ...
1. The priority principle of arc welding with electrodes
For the installation and welding of pipelines whose diameter is not too large (such as below 610mm) and the length of the pipeline is not...
In GMAW (gas metal arc welding) practice, horizontal welding is a position that many beginners have mixed feelings about. It’s easier than vertical or overhead welding, but if parameters an...
First, Welding cracks and pores are generated.
The moisture absorbed by the welding rod becomes gas under the action of the welding arc heat, which decomposes hydrogen, resulting in the formation ...
Important structures such as boilers and pressure vessels require safe penetration of joints, but due to limitations in structure size and shape, double-sided welding is sometimes impossible. A sp...
Introduction
Proper storage of welding consumables is often overlooked — but it directly affects welding quality, safety, and cost.
Incorrect storage can lead to:
Moisture absorption
Porosity an...
